RE: Carries and Junglers how do you gank and carry.
Like I said, its how I play my carries and I've had success with it, even a few times in ranked.
Sure its a good idea to farm non-stop, making the game extremely long, but with champions like Nocturne and Xin, you benefit more, as well as provide better early game positioning for your team, if you them a favor and get down your lane's enemy tower first.
LoL isn't meant to be played like DoTA, there are many tactics that can be useful, but they aren't nearly the same game, mostly because of the champion balance (albeit LoL's balance is very poor) and the skill curve.
Now you said you don't want to be ganked 1000 times until their jungle is fed, but there are champions who are efficient at avoiding ganks as well as pushing hard on lanes, whether you're solo or not. If you don't ward to make sure you know when the gank is coming, of course you're going to be destroyed. Map awareness is key, and I'm not saying you blinding act like a fool and feed the enemy team, but they are called carries for a reason, not farmers. Carries are supposed to give teams positional advantages.
As a Carry, you force the enemy team to change their plans, like how I see it, the less time their jungle is actually jungling, gives my teams jungle more time to steal his mobs as well as keep their jungles level down. Its about communication, if an enemy jungler is in a lane or dead, your jungle should be told and made aware, so they can go in and steal some of their jungle.
Of course the game is better played safe, but you can farm until the game is an hour long, but there honestly is no real fun in that, especially if you're playing kill happy champions.
As for the amount of gold a lane gets over jungle, it honestly depends. There are some champs who have awesome auto-attack animations making it easy to last hit, like Akali and LeBlanc. There are also champions with certain skills making farming a breeze but as well as keeping the enemy team from farming llike Morgana and Nocturne. I've found that I build faster on champions like Nocturne laning than I do in the jungle, and respectively end up ruining early game for other champions by not allowing them to farm. Often when the laning phase is done, the enemies in my lane are underleveled and keep out of fights to farm, while the rest of my team pushes down a lane and kills off their team.
And yes I'm level 30, I'm not mentally challenged, but a lot of people who are coming from DoTA are used to that style of playing being farm it up. That's good and I'm not saying its bad, but LoL allows for more agressive playing and doesn't have a negative effect for it. If you push down a tower first and weaken a second tower, you're doing your team a lot more of a favor than sitting in a lane farming until 20-30 minutes. That's just how I see it, and how I've won. Granted if you don't have a competent team, doesn't matter how many kills you get as a carry, you're more than likely not going to win anyways because of your teams ability to never engage and running away from fights, causing you to have wasted your time putting your team ahead.
I do understand the theory behind controlling minion waves and the enemies ability to farm, and it's helpful if you continue to farm while not letting them, I was a DoTA player myself, but that was years ago, and I was playing HoN for the longest time. But these two games punish aggressive playstyles while LoL encourages it. I don't think its that most PUGs dislike the idea of farming, its just farming often causes slow games and even Riot themselves have stated they want SR to be faster, and this causes what most people tend to do, play aggressive and get the game over faster. Sadly a lot of the time, people are fools and just play aggressive without being smart and cause the game to be short for a bad reason.
